To all whom t may concern.'

Be it known that I, WALTER CHALLINER, subject of the King of Great Britain and Ireland, and resident of Levenshulme, inthe county of Lancaster, England, have invented certain Improvements in l/Vheels, of which the following is a specification.

My invention relates to improvements in the construction and manufacture of metal wheels for road vehicles and has reference to that type in which the wheel is built up in parts, that is to say, usually a hub portion a number of spokes and a rim, the object beingto provide an improved.construction and manufacture of wheels more particularly intended for the heavier class of road vehicle, though its usefulness is not limited thereto since the same construction may be adopted lfor the lighter type of wheels.

My invention comprises a novel construction of hub, means for connecting the spokes thereto, an improved construction of rim and means for connecting the latter to the outer ends of the spokes together with other details of construction which vill be ,herein` after referred to.

My invention will be fully described with reference to the accompanying drawings in which- Figure 1 is a transverse section of half of a'wheel constructed inA accordance with my invention, Fig. 2 is aside elevation of a quarter of the wheel, Fig. 3 is a transverse section through two of the spokes on line l, 1 of Fig. 2, Fig. 4Q is a similarview to Fig.w2 of a modifiedoconstruction of wheel, Fig. 5 is a perspective view of one of the hub blocks employed in Fig. 4, Fig. 6 is4 a perspectiveview showing a modified form of hub block arranged in connection with spokes of barrel-shaped cross section, Figs. 7 to 9 are perspective views of modified forms of hub blocks arrangedin connection with spokes of different cross section.

In accordance with my invention I form the hub portion of the wheel in each of theA constrlictions shown in the drawings from separate segmental or hollow blocks a in conjunction with the inner ends of the spokes i5. That is to say, I employ a number of hollow blocks a which are roughly V- shaped in side elevation and of a segmental character, though I do not confine myself strictly to a vsegmental shape. The blocks are preferably hollow and fit between the inner ends of the spokes, the character of their joining faces with the spokes depending upon the cross section of the latter. Thus if the spokes are of girder section with the flanges c formingthe front and back edges or faces of the spokes or where such flanges lie in the front and back planes of I the wheel as ini/Figs. 1 to 3 and Fig. 9, the

hollow blocks are recessed at (Z at their side faces so as to lit within'the inner faces of the ilanges c and so that their extreme outer faces e' are flush with the outer faces of the flanges, though on the other hand the4 blocks may be made to fit between the inner faces of the flanges c and may-be welded to the latter where theyr join the spokes, that is to say, either at the edges of the latter or at-the opposite faces of the spoke webs and and at the inner and outer ends. The spoke flanges c are usually tapered or beveled oft` where they join together at l1, as shown in Fig. 2- and the central hole of the hub formed by the blocks-and spokes may be provided with a tubular sleeve (not shown) which may be removable or may be welded to the blocks and spokes, such sleeve receiving the usual axle sleeve as will be well understood, such latter sleeve being connected to the hub of the wheel b v transverse bolts passed through holes i shown in Fig. 1.

Fig. 9 shows blocks of a similar character to those already described except that the outer ends are not inclosed. Welding is carried out on the radial lines 'g as already described. In another form of block it may be provided with outer flanges y', Figs. Ilv and 5, adapted to overlap the flanges cof the girder spokes, or in other words each block would be recessed at -s on its converging sides to fit on the flanges of the spokes, the outer edges of the block flanges heilig beveled off' or left square as shown in Fig. 5 andv stopped short of each other so as to leave a space m. Fig. 4 between their joining edges when the whole of them are assembled. Or where the edges are beveled 0H Vshaped spaces are left but in both cases the edges do not touch thereby leaving the outer faces of the spoke flanges exposed to allow of welding taking place along the radial spaces m and so as tot'orin a. homogeneous connection during welding between the blocks and the spokes. vThe outer end ot'the blocks may stop ott' on the concentric line fn, Fig. 5 or the recessed embracing portions ot the blocks may be extended radiallybeyond the line n' as shown in rigs. It and 5.

ln Fig. G a modification of thc arrange. nient just described is indicated, the blocks being altered in construction to suit the cross section of the barrelshaped spoke indicated.

Fig. 7 indicates blocks adapted to the cross section of T-shaped spokes, the plane fares ofthe bhickslniving extending flanges'to embrace the flange c and also the'- web of the spoke. The construction will be well understood from the description given of the other modifications previously referred to.

Fig. 8 indicates another modified form of block adapted to spokes of the section indirated in the figure` welding taking place along the edges oi the front. and back webs while the inner webs are embraced by the recessed portions of the blocks.

l do not confine nrvselt to any particular cross section o1" the spokes but. as will have been gathered from the 'foregoing description spokes of varying cross sections may be employed and the blocks be altered to correspond but generallyY the blocks and spokes would be connected together substantially in the manner previmisly described.

M v invention also relates to improved constructions of rini for the wheels and consistsi'in one case ot making the rim from a number ot' segments 71 as shown in Fig. 4. 'lhe rim segments p are provided with inwardly projecting half sockets r/. shaped to receive the outer end portionsof the spokes. The extreme ends ot the. spokes s are arranged to abut against the bottoms not these sockets, and the end portions of the spokes are welded to the edges of the-half sockets at the radial openings u normally formed between the edges of the half sockets. The rim segments are welded together Vat the half sockets, and the tire 10 may be formed separately and secured upoirthe segments g?, or it may be formed integral with them.

\Vhat l claim is: l. A metallic wheel, comprising radial spokes the innery ends of which extend to thecentral opening ot' the hub, and suitably shaped hollow hub-blocks ar anged circumyferentialtv vin and filling the angular spaces between t-lieim1er end portions ot the said spokes, said blocks being welded directly to the said spokes. 2. A metallic wheel, comprising radial spokes provided with longitudinal flanges and having their inner ends arranged to extend to the central opening of the hub, and hollow hub-blocks provided .with recesses for engaging the spoke flanges, said blocks being arranged circumferentially in and filling the angular spaces between the. inner end portions of the said spokes and being welded directly to them. i

fi. A metallic wheel, comprising radial spokes, and a rim formed of riin sections which are welded together and 'provided with hallc sockets which tit around the outer end portions of the said spokes, the outer lends ot thespokes being arranged to abut against the bottoms of the sockets, and the side portions of the Spokes heilig welde'd directly to the edges of the half sockets at the radial openings between them.

ln testimony whereof I have hereunto set my hand in the presence of two witnesses.
